The division was activated again in 1964, when England once again supported two fighter wings. However by 1966, the division's units had deployed overseas, primarily to support the War in Vietnam. By the summer of 1966, the division was stripped of its manning. In October, the 834th transferred on paper to Tan Son Nhut Airport, where it assumed responsibility for controlling all airlift in South Viet Nam.

As American forces were being withdrawn from Vietnam, the division moved to Little Rock Air Force Base, Arkansas and assumed command of tactical airlift wings located in the western portion of the United States. In December 1974, the division was transferred to Military Airlift Command (MAC) along with other theater airlift units. One month later, it was inactivated and its units transferred to Twenty-Second Air Force.

The division returned to the Pacific in 1978 as the 834th Airlift Division when it assumed responsibility for MAC assets in the Pacific and acted as the airlift adviser for Pacific Air Forces (PACAF). During Desert Storm its commander acted as the commander of airlift forces in Saudi Arabia. The 834th was inactivated when PACAF assumed responsibility for airlift in the Pacific from MAC.

In late April 1966, the remaining fighter wing at England, the 401st, was transferred to Torrejon Air Base, Spain and in August, the 31st Tactical Fighter Wing at Homestead was reassigned to the 836th Air Division, while all support activities at England were reassigned to the 1st Air Commando Wing, which had moved to England in January, leaving the 834th without a mission.[9][3][10]

On 15 October 1966 the 834th moved without personnel or equipment to Tan Son Nhut Air Base, South Vietnam, to become the controlling agency for theater airlift operations in South Vietnam. It served as a single manager for all tactical airlift operations in South Vietnam, using air transport to haul cargo and troops, which were air-landed or air-dropped, as combat needs dictated.[1] The division included the 315th Air Commando Wing, which operated Fairchild C-123 Providers, and the 483rd Troop Carrier Wing, which activated the same date the division moved in October 1966 as the parent unit for former US Army de Haviland Canada C-7 Caribous which had transferred to the Air Force. The division also included the 2nd Aerial Port Group, which moved to Tan Son Nhut from Tachikawa Air Base, Japan.[11]

In addition, 834th had operational control over 315th Air DivisionLockheed C-130 Hercules assigned on temporary duty in South Vietnam.[note 4] PACAF was reluctant to permanently station C-130s in Vietnam because of the additional support personnel required in an area with a mandated troop ceiling and crowded bases and the flexibility that would be lost in scheduling the planes, which provided airlift throughout the western Pacific.[12] Detachment 1 controlled C-130s operating from Tan Son Nhut while Detachment 2 controlled operations from Cam Ranh Bay Air Base. These replaced Detachments 4 and 5 of the 315th Air Division and were joined by Detachment 3 at Tuy Hoa Air Base by 1968.[13] In addition, the 834th supervised transport operations (primarily Douglas C-47 Skytrains) of the Vietnamese Air Force and a squadron of the Royal Australian Air Force.[note 5] The 834th's 315th Wing also performed defoliation missions.[1]

About one third of the division's strength was in the 2d Aerial Port Group, which had three subordinate squadrons with cargo handling detachments at 42 locations in Vietnam[14] The 2d Aerial Port Group also contained combat control teams and mobility teams that could be deployed to remote locations as needed.[15][note 6] Prior to the movement of the 834th to Vietnam, the 315th Wing had been performing the aerial port mission.[16]

The division's C-130s participated in Operation Banish Beach in 1967. In this operation, the transports performed free-fall airdrops of drums of diesel fuel or JP-4 The fuel was then ignited by fighters dropping napalm or by the C-130s dropping smoke grenades on the fuel to clear large forested areas. The Banish Beach technique was practiced operationally at the request of the Marine Corps to support Operation Allen Brook.[13]

The initial attack by the North Vietnam Army on 21 January 1968 gouged holes in the runway, but Seabees began to repair the runway damage. However, airlift aircraft landing or taking off at Khe Sanh could now routinely expect to encounter enemy fire and, once landed, attempts by the enemy to destroy them by mortar fire. Additionally, the lighting system for night landings had been destroyed.[21]

The most critical initial need was replenishment of the base's stored munitions, 98% of which had been destroyed in the initial attack. The division diverted C-123s (the largest airlift aircraft capable of using the damaged runway) to meet this need. On return flights, division planes flew out refugees[21] and casualties.[14] In the first two days, the division was able to replenish 120 tons of munitions, conducting night operations by the light of flares. By the end of the month, runway repairs permitted C-130 operations to resume.[22] Division aircraft landing at Khe Sanh were referred to as "mortar magnets" because of their attractiveness as targets for enemy fire. The transports used a technique called "speed offloading" to deliver their cargo. Runners were fixed to the planes' rear ramps and onboard pallets, and as the planes taxied, the pallets were released and rolled off the planes impelled by the planes' motion and "vigorous kicks" by their loadmasters.[23] Even adding in additional time to onload passengers, a typical C-123K sortie was on the ground for only three minutes.[24]

On 5 February, a division-controlled C-130 from the 345th Tactical Airlift Squadron transporting ammunition and a medical evacuation team to Khe Sanh was hit by a shell that ignited ammunition boxes in the cargo compartment. The crew fought the fire while the pilot Lt. Col. Howard Dallman, backed up the plane to an area at the far end of the runway, where, if the ammunition exploded, it would not destroy the runway and support facilities nearby. The crew extinguished the fire and helped offload the ammo boxes without further damage. Lt. Col Dallman, received the Air Force Cross for his actions.[25]

C-130 using LAPES in Vietnam

By 7 February, seven C-130s had received battle damage approaching or on the ground at Khe Sanh. Seventh Air Force decided the Hercules was too valuable an asset to risk in landings there, except for four high priority missions. Although air drops by the planes continued, for the next month, missions requiring landings were limited to those carried out by the 315th Wing's Providers or the 483d Wing's Caribous.[26] Hercules aircraft continued to deliver cargo using the Container Delivery System and LAPES. LAPES deliveries, however damaged the runway, although the damage was limited to the far end of the runway and did not impede C-123s.[27] When equipment for LAPES ran into short supply, the 834th was able to scrounge ten sets of the abandoned Ground Proximity Extraction System, which used cables and arresting hooks to extract cargo from low flying cargo planes and install them at Khe Sanh.[28]

Division losses at Khe Sanh amounted to three C-123s, plus one C-130 lost after the siege had been officially lifted.[29]

On 10 May 1968, The special forces camp at Kham Duc in the central highlands near Laos came under heavy mortar fire and was ordered to be evacuated. On 12 May, during evacuation efforts, an ArmyBoeing CH-47 Chinook and two division C-130s were disabled by enemy fire. One C-130 burst into flames at the end of the runway, killing all aboard. The final C-130 took off thinking it had boarded the last of the men on the ground. As the Viet Cong overran the forward outpost and established gun positions on the airstrip, eight aircraft were destroyed and the C-130 on the runway reduced its usable length to only about 2,200 feet. However, the three-man combat control team, in charge of directing the evacuation, was still on the ground searching for survivors.[30]

Informed that three men remained behind, Lt Col Joe M. Jackson of the division's 311th Air Commando Squadron dove his C-123K from 9,000 to land at the field. Unable to slow by reversing his propellers,[note 8] he jammed on the brakes and skidded halfway down the runway. The three combat controllers jumped from a culvert next to the runway and leaped into the open rear cargo door. A 122 mm rocket, fired from just outside the perimeter stopped only 10 meters from the plane. It did not explode. Jackson taxied around the shell and took off under heavy fire from the hills on either side of the camp. For this rescue, he was awarded the Medal of Honor[30]

As American participation in the War in Vietnam lessened, the division saw changes to its mission. During the summer of 1971, its 315th Wing began training Vietnam Air Force crews on the C-123, preparing them to assume an expanded airlift mission.[16] As other wings inactivated their squadrons that remained in country were transferred to the 315th and 483d Wings and the division found itself performing close air support, interdiction, electronic warfare and psychological warfare missions in 1971.[16][31][note 9] During its last few months, the 834th worked toward passing combat airlift control to Seventh Air Force."[1]

From 1972 until it was inactivated, "the division supervised . . . C-130 tactical airlift operations and participated in a series of tactical airlift exercises and joint training missions with United States Army units. Squadrons and detachment-size elements frequently deployed to points in Europe, the Panama Canal Zone, Africa, Thailand, and elsewhere. The 834th flew many humanitarian missions to such widespread places as Africa, the Philippines, Colombia, and Honduras."[1]

The division was transferred to Military Airlift Command (MAC) on 1 December 1974 as part of TAC's turnover of the theater airlift mission to MAC. However, MAC inactivated the 834th on 31 December 1974,[1] and transferred its assigned airlift wings to Twenty-Second Air Force.[34]

The division was renamed the 834th Airlift Division and reactivated at Hickam Air Force Base, Hawaii in October 1978. It assumed responsibility for managing all MAC resources in the Pacific area.[1] The 834th provided a single commander for MAC airlift units in the Pacific theater and its commander also served Pacific Air Forces (PACAF) as the special assistant for airlift.[35] It commanded theater airlift forces for PACAF; performed airlift war planning and exercise planning and operated aerial ports for the air movement of personnel, cargo, equipment, patients, and mail.[1]

The division originally exercised its airlift management function through the Pacific Airlift Center, while its airlift support units spread throughout the Pacific were controlled by the 61st Military Airlift Support Wing. However, reorganizations in 1980 and 1981 eliminated this intermediate level of command and airlift support units were assigned directly to the division, as were airlift managers.[37]

The division's C-130 fleet was reduced in 1989 by the removal of aircraft from Clark Air Base in the Philippines. In conjunction with this reduction, the division's 374th Tactical Airlift Wing moved its flag to Yokota Air Base, Japan, where it assumed the personnel and equipment of the 316th Tactical Airlift Group, which was inactivated.[36] In 1990 the division's area of responsibility was further expanded when MAC units in Alaska were assigned to it.[38]

During Operation Desert Storm, the division commander, Brig Gen James F. Hinkel, served as the commander of airlift forces in Saudi Arabia. Shortly after the end of that operation, in June 1991, the eruption of Mount Pinatubo required the evacuation of military and dependents from Clark Air Base. The division directed the evacuation in what was termed Operation Fiery Vigil. The commander of the division's 374th Wing acted as the commander, Airlift Forces, Joint Task Force Fiery Vigil. Operations were conducted from Naval Air Station Cubi Point and continued through July.[39][40]

When the decision was made not to return forces to Clark, the division's 624th Military Airlift Support Group was inactivated in November 1991.[39] The division was inactivated in April 1992 and its remaining units were inactivated or transferred as PACAF assumed responsibility for theater airlift in the Pacific area.[1][39][41]
